I had a few issues with the original design:
1. I did not see a point in having a scroll wheel and a trackpoint. That's one of the things that they're awesome at (and it increases the cost/complexity)
2. I don't see a reason to rearrange the control/alt/meta keys.
3. You don't need two backspaces, Might as well use the key for more functionality.
4. I love page up/down!
looking good, i far prefer this, delete should also use fn to become ins
